CHARLES A. SLAUGHTER, OF JACKSONVILLE, ILLINOIS.

ROAD SCRAPERAND GRADER.

SPECIFICATION forming part of Letters Azatent N o. 718,029, datedJanuary 6, 1903.

Application filed April 1. 1902. Serial No. 100,925. (No modeLl To allwhom, it may concern.-

Be it known that LCHARLES A. SLAUGETER,`

a citizen of the United States, residing at Jacksonville, in the countyof Morgan and State of Illinois, have invented cert-ain new and usefulImprovements in Road Scrapers and Graders; `and I do declare thefollowing to be a fu1l,rclear, and exact description of the invention,such-as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the figures of reference marked thereon, which form a part ofthis specification.

This invention relates to improvements in road Scrapers and graders ofthe drag type.

The improvement comprehends a structural arrangement of elements tolevel a road as the apparatus is draggedover the surface and at the sametime deiects any surplus material not utilized when at first encounteredby the grader in such direction that it will be again subjected toanother grading action and finally deliver what is left toward thecenter of the road-bed or, better, toward the center of the line ofdraft.

It is also'my purpose to construct a sectional grader which can beconveniently elevated should an obstruction be met with- In thedrawings, Figure l is a perspective view of my improved road scrapingand grading apparatus. Fig. 2 is a front elevation of the same to moreclearly disclose the arch connection between the drags. Fig. 3 is a topplan view, and Fig. 4 is a side elevation.

The same numerals refer to like parts throughout all the figures.

l and 2 indicate lwhat I shall term, respectively, front and rear drags.Disposed intermediate the two drags are spaced-apart `the opposite endsof the beams 9 9 are connected tothe rear of the beams 3 3 by similarbraces 12 12.

By referring more particularly to Fig. 3 it will be observed that theforward ends of the beams 9 extend considerably in advance of the rearof the beams 6 and that this eXtension may be changed to accord withvarying circumstances; also that the angle of the rear drag may bealtered I provide a series of openings 13 in each beam 9, and bolts 14pass through openings in the ends of the braces l1 and 12 and selectedones of the openings 13. It will be further noted that the rear ends ofthe beams 9 do not come together. It is to adj ust this space also thatthe openings 13 and bolts 14 are used.

The .parts thus assembled, the operation is substantially as follows:The scraper and grader is drawn over the ground in the direction of thearrow 15 in Fig. 3, and by reason of the steel wearing or cutting platesbeing on the front of Jthe beams 6 a cutting edge is formed whichreadily scrapes or shaves the surface of the road smooth. In so doingthe dislodged earth is carried along, and if ruts or other hollows arepresent such loosened earth lls them up; but should more earth bedislodged than there are ruts to fill, or if by some reason the ruts donot receive a suffe cient quantity of earth to pack them tight, theoperation is repeated-that `is to say, by the peculiar arrangement ofthe two drags the surplus earth from the front drag is deiiected towardits outer ends and against the extended portions of the ends of thebeams 9 of the rear drags, so that now the direction of the' travel ofthe earth is changed, although the i operation and function of the dragis identical with that of the front drag.

Any unevenness omitted by the front drag is IOC forthwith obviated bythe rear drag, and correspondingly the earth is dislodged and gathered,and ruts, &c., treated as at first are sure to be packed and filled bythe rear drag.

In an apparatus of this type there is almost to a certainty to be afinal surplus of earth, and various expedients have been employed todirect it in some cases toward the center,A

others again away from the center of the machine, and others haveendeavored to spread it. By my improvement I combine all of thesevarious methods of disposing of vthe surplus earth, enabling me toreduce to a minimum any excessive amount of final surplus and yet gatherand to a degree separate any rubbish and stones and deliver them in arow in approximately the center of the line of draft.

Should any unevenness be presented in the road, the hinge connectionbetween the drags will allow the various beams to accommodatethemselves. Hence the grading will not be effected by such conditions.Moreover, the arch-braces will serve to make a further resilientconnection and assist to insure the road being thoroughly scraped.

My invention therefore possesses many decided advantages over thepresent state of the art, and it is thought its advantages and meritswill be fully comprehended by those skilled in the art to which itappertains.

What I claim as new is l. A scraping and grading apparatus comprising afront drag, and a rear drag, arranged at an angle to each other,substantially as described, whereby the material scraped by one drag isthrown into the field of the other drag.

2. A scraping and grading apparatus comprising a front drag arrangedatan angle, and a rear drag arranged at a different angle than the frontdrag, the front of the rear drag extending in advance of the terminationof the front drag, substantially as described.

3. A scraping and grading apparatus comprising a front drag arranged atan angle, a rear drag arranged at a different angle, the

Afront of the rear drag extending in advance of the terminal of thefront drag, and archshaped braces connected to the front and rear dragsto form a space between the two drags, substantially as described.

4. A scraping and grading apparatus comprising a front drag, a rear dragarranged at a different angle, the front of the rear drag extending inadvance of the terminal of the front drag and means adjustablyconnecting the two drags for changing the angles thereof, substantiallyas described.

5. A scrapingand grading apparatus comprising a front drag composed of apair of angularly-arranged beams, a pair of beams intermediate saiddrag, a hinge connection between the said beams, hinges connecting theintermediate beams and the beams of the drag, a rear drag composed of apair of angularly-disposed beams which extend forwardly beyond theterminal of the front drag, means connecting the frontdr'ag and the reardrag, means connecting the rear drag-beams and the intermediate beams,and means for changing the angle between the two drags, substantially asdescribed.

6. A scraping and grading apparatus comprising a pair of beams,hingessecuring said beams together, a pair of beams hinged at or near thefront end of the aforesaid beams, forming a front drag, and a pair ofbeams positively secured at or near the rear end of the first-namedbeams forming a rear drag, the forward ends of the beams of the reardrag extending beyond the terminal of the front drag, substantially asdescribed.

7. A scraping and grading apparatus comprising two sections exiblyconnected, each section being composed of an angularly-arranged frontbar, a rearwardly-extendingbar which is at a dierent angle than thefront bar, means for supporting the rear end of the rearwardly-extendingbar, means connecting the latter bar and the front bar whereby a spaceis formed between the two, and means for maintaining a space between theends of the rearwardly-extending bars when the two sections are securedtogether, substantially as described.

8. A scraping and grading apparatus comprising a front, approximatelyA-shape drag, a rear approximately A-shape drag,said drags diverging inopposite directions, the rear drag extending at its front end beyond therear of the front drag while the rear end of the rear drag is open, andmeans connecting the two drags together, whereby a space is formedbetween them, substantially as described.

9. A scraping and grading apparatus comprising means for scraping andgrading the earth and simultaneously forcing the surplus earth from theplane of action, means for simultaneously gathering the said surplusearth and scraping and grading in the plane of the first-named means,but in an opposite direction thereto, substantially as described.

l0. A scraping and grading apparatus comprising means for scraping andgrading the earth and simultaneously forcing the surplus earthoutwardly, means for simultaneously gathering said surplus earth andscraping and grading in the plane of the firstnamed means but toward thecenter, substantially as described.

1l. A scraping and grading apparatus comprising a diverging drag, and aconverging drag, the end of one drag extending beyond the other drag,substantially as described, whereby the material scraped by one drag isthrown into the eld of the other drag.

In testimony whereof I aliix my signature in presence of two witnesses.
